Delhi Chief Minister Arvind Kejriwal and Amarinder Singh on Monday locked horns on social media after the AAP chief accused the Congress’ Punjab CM hopeful of using “drug money” in his campaign. Singh put out a stinging response to Kejriwal, saying he was “hallucinating” and seeing things that “don’t exist”. The two leaders have been increasingly trading barbs on Twitter as the Assembly election nears.

Kejriwal has been alleging a “nexus” between Congress and the ruling Akalis in poll-bound Punjab. He has dubbed Singh their “joint chief ministerial candidate”.

“Sir, Badals closed corruption cases against u just a few months before elections. Why? Punjab asking what’s the deal?” Kejriwal had tweeted yesterday, responding to which Singh asked the AAP chief to “set his own house in order, before he sets his sights on Punjab”.

Kejriwal was referring to Punjab Vigilance Bureau’s clean chit to Singh in his alleged role in the Amritsar Improvement Trust land scam case.
